After I found a niche, I hired an US writer to write some review articles for me. She wrote 10 high quality articles to compare different products on Amazon in my niche. Each article has about 1000 words. Then I built a wordpress blog and posted the articles.
One thing I forgot to mention, I bought an expired domain for the site. It's an old domain with some backlinks in the health niche.(my niche site is also in the health niche). So this domain is perfect for me. My thought was I could get a competition advantage at the beginning by using this domain. So my site already had some backlinks and authority when I started to build the site. And then It was indexed and got in the google top 100 for several keywords very quickly.
The next thing of course should be making my google ranking higher. So I built some backlinks. One of the easiest ways is to do guest posting. I contacted some bloggers. 4 of them replied, but 3 bloggers asked for money to get my articles published. So I only get 1 guest post link. Paid link can be a choice, but I was not interested.
Then I tried another technique---infographic link building. This is a great method. You can use the same infographic to get backlinks again and again. You don't have to write many articles to get backlinks like you do guest posting. And people are often interested in this kind of content. Because in some niches, there are not many infographics. It's a content gap!
It's pretty simple to do this. You just find some pages that has already linked to some similar resources. Then you email the site owners. Your infographic is similar to the resources they linked to on their pages. So they will be interested in linking to your infographic, right?
So I sent outreach emails to some site owners in my niche. I didn't send many emails, less 100. And two people linked to my infographic. One of them gave me over 50 links, so the link appeared on many pages of her site. This site passed so much link juice to my site! These links are very high quality. Because they are from 2 authorities in the same niche as my site. Relevancy is the New PR.
Now the site has 59 backlinks according to Ahrefs. And it's ranking in google top 100 for over 170 keywords. Ranking in 4th or 5th page of google for some keywords with over 1000 monthly searches.
